PIPE CLEANSING TOOL v Filed Jan. 27, 1959 Patented Sept. 9, 1941 HPE CLEANSING TOOL Stellan Eugn Lindh, Valasen, Sweden Application January 27, 1939, Serial No. 253,193 In Sweden January 28, 1938 1 Claim.

The present invention refers to a pipe cleansing tool adapted to scrape ofi carbon substance deposited on the inside walls of the bowls of tobacco pipes, as well as to a tool of this type in combination with a device for the cleaning of the pipe stems.

According to the invention the pipe cleansing tool is provided with a scraping member consisting of a hollow metal cylinder with a smooth outer surface and terminated by an annular toothed scraping surface having a somewhat larger diameter than said smooth cylindrical portion, said scraping surface being adapted to scrape loose the carbonaceous deposits on the side walls of the pipe bowl.

The invention is illustrated in the accompanying drawing. Fig. 1 shows a tool adapted to scrape oif carbon deposits from the side walls of pipe bowls, viewed from the front, and Fig. 2 shows the same tool in side elevation.

The tool represented in Figs. 1 and 2 is made in the form of a hollow smooth metal cylinder at provided with teeth 17 at the annular lower end thereof. The lower end of the cylinder a.

will thus form a scraping surface, the outer diameter of which as indicated at c is somewhat larger than the smooth cylindrical portion of the tool thus insuring the presentation of a small clearance space around the smooth cylindrioal portion. This space enables the tool to be readily operated in a pipe bowl without danger of breakage thereof. preferably provided at the upper end thereof with a thumb grip d for the turning of the tool.

Having now particularly described the nature of my invention and the manner of its operation, what I claim is:

A pipe cleansing tool for scraping off carbonaceous substances deposited on the inside walls of the bowls of tobacco pipes, said tool being provided with a scraping member consisting of a hollow metal cylinder with a smooth outer surface and terminated by an annular toothed scraping surface the outer diameter of which is somewhat larger than the diameter of said smooth cylindrical portion.
